Pachyveria plant named ‘TSAECH1702’

ABSTRACT

A new and distinct  Pachyveria  plant  Pachyphytum glutinacaule  x  Echeveria hookeri,  named ‘TSAECH1702’ which is characterized by long and narrow succulent foliage with an upwardly curved aspect and an upright attitude, light greyed-green juvenile foliage with a white to light blue hue at and near the center of the rosette, foliage which becomes progressively suffused with yellow-green with age, mature foliage towards the outermost whorls of the rosette which is generally colored yellow-green with a blue hue, as well as the stability of these characteristics from generation to generation.

Latin name of the genus and species: The Latin name of the genus andspecies of the novel variety disclosed herein is Pachyphytumglutinacaule x Echeveria hookeri.

Variety denomination

The inventive variety of Pachyveria hybrid disclosed herein has beengiven the variety denomination ‘TSAECH1702’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rightsapplication number 2017/1147, filed Apr. 25, 2017, which is hereinincorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: ‘TSAECH1702’ is an intergeneric hybrid seedling selectionresulting from the controlled pollination of an unnamed Pachyphytumglutinacaule plant (not patented), the seed parent, with an unnamedEcheveria hookeri plant (not patented), the pollen parent. The crossingwas made by the inventor in the autumn of 2013 at a commercialgreenhouse in Heerhugowaard, the Netherlands. In the summer of 2015, oneseedling was observed which exhibited unique growth and foliagecharacteristics. The seedling was isolated for further evaluation inorder to confirm the distinctness and stability of the characteristicsfirst observed. Upon confirmation of distinctness and stability,‘TSAECH1702’ was selected for commercialization in the autumn of 2015.

Asexual Reproduction: Asexual reproduction of the new cultivar‘TSAECH1702’, by way of rooting leaf cuttings, was first initiated inthe summer of 2016 at the inventor's commercial greenhouse inHeerhugowaard, the Netherlands. Through four subsequent generations, theunique features of this cultivar have proven to be stable and true totype.

SUMMARY OF THE INVENTION

The cultivar ‘TSAECH1702’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype. The followingtraits have been repeatedly observed and are determined to be the uniquecharacteristics of ‘TSAECH1702’. These characteristics in combinationdistinguish ‘TSAECH1702’ as a new and distinct Pachyveria cultivar:

-   -   1. ‘TSAECH1702’ exhibits long and narrow succulent foliage with        an upright attitude, arranged in basal rosette; and    -   2. ‘TSAECH1702’ exhibits thick, spatulate to obovate foliage        with an upwardly curved aspect; and    -   3. ‘TSAECH1702’ exhibits very light greyed-green juvenile        foliage with a white to light blue hue at and near the center of        the rosette; and    -   4. ‘TSAECH1702’ exhibits foliage which becomes progressively        suffused with yellow-green, with age, towards the outer whorls        of the rosette; and    -   5. ‘TSAECH1702’ exhibits mature foliage at the outermost whorls        of the rosette which is generally colored yellow-green with a        blue hue.

FIG. 4 illustrates, as nearly true as it is reasonably possible to makethe same in color photographs of this type, the abaxial surface of themature foliage ‘TSAECH1702’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in January of 2018describe averages from a sample set of six specimens of 6 months old‘TSAECH1702’ plants grown in 10 cm nursery containers at commercialgreenhouse in Heerhugowaard, the Netherlands. Plants were produced usingconventional greenhouse production protocols for Echeveria andPachyphytum plants which consisted of minimal irrigation and fertilizerapplications, and chemical pest and disease control measures againstmealy bug and Botrytis as required. Plants were grown underapproximately 50 percent shade after propagation and later exposed tofull sun once they began to mature. No photoperiodic treatments orartificial light was given to the plants.

Those skilled in the art will appreciate that certain characteristicswill vary with older or, conversely, with younger plants. ‘TSAECH1702’has not been observed under all possible environmental conditions. Wheredimensions, sizes, colors and other characteristics are given, it is tobe understood that such characteristics are approximations or averagesset forth as accurately as practicable. The phenotype of the variety maydiffer from the descriptions set forth herein with variations inenvironmental, climatic and cultural conditions. Color notations arebased on The Royal Horticultural Society Colour Chart, The RoyalHorticultural Society, London, 2015 (sixth edition).
